After Spring boot server initialization,it throws InvocationTargetException and ApplicationContextException - spring

Question

I am a newbie to spring and I am trying to implement a simple Spring boot application which will parse a json string and write it to a file.
Here is the code of my main class
package com.example;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
//#SpringBootApplication
#Configuration
#ComponentScan
#EnableAutoConfiguration
public class Application extends SpringBootServletInitializer {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
#Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
return application.sources(applicationClass);
}
private static Class<Application> applicationClass = Application.class;
}
The rest controller definition is below
package com.example;
import java.io.*;
import javax.servlet.http.HttpServletRequest;
import org.json.simple.JSONObject;
import org.json.simple.parser.JSONParser;
import org.json.simple.parser.ParseException;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
#RestController
public class Controller {
#RequestMapping(path="/api",consumes=MediaType.APPLICATION_JSON_VALUE)
public String insertData(#RequestBody String rawJsonData,HttpServletRequest request) throws ParseException, IOException{
JSONParser jparser=new JSONParser();
Object jsonObj=jparser.parse(rawJsonData);
JSONObject jObject=(JSONObject)jsonObj;
FileWriter filewriter=new FileWriter(new File("C:\\Users\\Desktop\\Aayushi.txt"));
filewriter.write(jObject.toJSONString());
return rawJsonData;
}
}
The updated pom.xml file is as defined below

If I run this code as Run as->Maven Build, then I get the following errors and I am not sure why these errors are coming.
Updated error log:

Answer 1

Please refer to the Traditional Deployment documentation of Spring Boot.
To stop the embedded servlet container from interfering with the target container you need to change packaging to war (which you have done) and mark the embedded runtime as as "provided" scope.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-tomcat</artifactId>
<scope>provided</scope>
</dependency>
Do not exclude it.

Answer 2

Spring-boot by default starts tomcat container. But in your pom you are excluding it. And you are not specifying any other container as well. Either remove this exclusion or add this dependency to start jetty
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-jetty</artifactId>
</dependency>

Answer 3

you are not use #ImportResourcetry into start of the class please try this code.
#SpringBootApplication
#ImportResource("classpath:abc-server.xml")
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
